Resumen

DE BRODTKORB, Milka K. Precious metaltellurides and other Te-bearing minerals in different paragenesis of Argentina: A review. Rev. Asoc. Geol. Argent. [online]. 2009, vol.64, n.3, pp. 365-372. ISSN 1851-8249.

Severalpolymetallic deposits containing tellurides and Te-bearing minerals occur indifferent geologic terrains of Argentina. Tellurides with Ag and /or Au arewidespread in meso and epithermal environments; they are structurallycontrolled and genetically related to Jurassic or Miocene-Pliocene volcanism.These species are represented by calaverite, hessite, stützite, krennerite,sylvanite, petzite and cervellite. Other Te-bearing minerals are present notonly in epithermal deposits but also in different assemblages such asintraplutonic W deposits, skarn and mafic-ultramafic bodies. They are Te,altaite, nagyágite, melonite- merenskyite, tetradymite, telurobismuthite,kawazulite, Te-canfieldite and goldfieldite. Paragenesis of the differentdeposits and chemical data of the minerals are given.

Palabras clave : Tellurides; Te-bearing minerals; Precious metal minerals; Epithermal deposits.
